The presented paper studies the effect of the casting technology on the corrosion resistance of Co-Cr-Mo alloy. The investigations were conducted on a commercial alloy with the brand name ARGELOY N.P SPECIAL (Co-Cr-Mo) produced by Argen as well as the same alloy melted and cast by the lost wax casting method performed by a dental technician. The corrosion behavior of the dental alloys in an artificial saliva was studied with the use of the following electrochemical techniques: open circuit potential and voltammetry. After the electrochemical tests, studies of the surface of the examined alloys were performed by means of a scanning electron microscope with an X-ray microanalyzer. The results of the electrochemical studies show that the dependence of the corrosion resistance on the microstructure associated with the recasting process is marginal. The results of the electrochemical studies of the considered alloy clearly point to their good corrosion resistance in the discussed environment.Keywords: cobalt alloys, corrosion resistance, method of wasted wax, microstructureZbadano wpływ technologii odlewania na odporność korozyjną stopu Co-Cr-Mo. Badaniom poddano stop komercyjny o nazwie handlowej ARGELOY N.P SPECIAL (Co-Cr-Mo) firmy Argen oraz ten sam stop przetopiony i odlany przez technika dentystycznego metodą traconego wosku. Zachowanie korozyjne badanego stopu w środowisku sztucznej śliny zostało zbadane przy użyciu technik elektrochemicznych: pomiaru potencjału bezprądowego, woltamperometrii cyklicznej.Po przeprowadzeniu badań elektrochemicznych wykonano badania powierzchni badanego stopu przy pomocy elektronowego mikroskopu skaningowego z mikroanalizatorem rentgenowskim. Wyniki badań elektrochemicznych wskazują, że na odporność korozyjną oraz mikrostrukturę stopu proces powtórnego odlania wpływa jedynie w niewielkim stopniu. Wyniki badań elektrochemicznych rozpatrywanego stopu wskazują jednoznacznie na ich dobrą odporność korozyjną w rozpatrywanym środowisku.

The paper discusses recent fieldwork at the Meroitic settlement site of Selib 2, a town located on the west bank of the Nile between the Third and Fourth Cataracts, investigated by the Banganarti/Selib Polish Archaeological Mission since 2010. The fieldwork was concentrated on uncovering the earliest occupation strata from the 1st/2nd century CE. Two mud-brick buildings were fully excavated, along with contemporaneous occupational horizons, yielding, among others, unique bell-shaped decorated vessels, a copper plate, and a female clay figurine. Storage jars used as ovens and cooking places were present in all phases and can be considered as a characteristic furnishing of the explored households. Moreover, an archaeological reconnaissance extended the boundaries of the settlement eastward, providing new data for studies of the settlement plan and its various stages of development.

In the course of two seasons in 2012 and 2013 the team carried out excavations and research on the living quarters alongside the fortifications of Banganarti, including a large building (E.1) and eastern tower. Work on the restoration/conservation of the Upper Church progressed according to plan, combined with limited iconographic studies. The team also worked at the sites of Selib and Soniyat. At Selib explorations continued at three locations. The phasing of the church at Selib 1 was established (separate report by A. Cedro), leading to a reconstruction of the plan of the earliest two buildings. A Meroitic(?) structure was investigated at Selib 3 and the Meroitic settlement at Selib 2 continued to be investigated (separate report by R. Hajduga and K. Solarska). A tachymetric plan and magnetic map of the environs of the Kushite temple at Soniyat was accomplished, recording a huge building (palace?) of apparently Kushite date (Napatan ceramic forms and Egyptian imports dating from the Third Intermediate Period) to the north of the temple. A separate team undertook a reconnaissance in regions scheduled to be flooded due to new dam construction projects in Kajbar and Shereik (Third and Fifth cataracts), staying on to record in detail a number of Makurian fortresses.
